Our atm network in san diego was the full base 16 hex for the 13 byte nsap prefix of all the atm switches in our 4-level PNNI cloud
This may be slightly off topic of ISIS practices though
But, yeah, we didn't encode any switch mgmt. ip into the nsap addressing as I recall... just the pnni peer groups had hex identities

I've always wondered about folks' opinions about one thing, though:
In y'all's opinion, do you prefer/recommend using base-10 digits or hex
in your NSAP addresses? I like the former for readability, but the
latter can (could) be better for automation. Maybe.
I got into a heated argument about this once with ATM back in the day,
but my brain's to frazzled to remember the takeaways.
